%s EDISON RcMano P. Caouse v.c. %sant Docket No. 50-346  %.,9w, License No. NPF-3 Serial No. 1074 August 27, 1984 Director of Nuclear Reactor Regulation Attention: Mr. John F. Stolz Operating Reactor Branch No. 4 Division of Operating Reactors United States Nuclear Regulatory Commission Washington, DC 20555

Dear Mr. Stolz:

Under separate cover, we are transmitting three (3) original and forty (40) conformed copics of an application for Amendment to Facility Operating License No. NPF-3 for the Davis-Besse Nuclear Power Station Unit No. 1.

This application requests that the Davis-Besse Nuclear Power Station Unit 1 Technical Specifications, Appendix A, be revised to reflect the changes attached. The proposed changes include:

1. Section 4.4.9.1.2, Table 4.4-5 and Bases

2. Section 4.7.1.2 The two attachments identify the proposed changes and its safety evaluation and significant hazard consideration. Item 1 concerns revision to the Reactor Vessel Materials Irradiation Surveillance Schedule to reflect the change in operating cycle length. The change is from 12 to 18 month refueling, cycle with anticipated reduction in accumulated neutron fluence of the reactor vessel material. Also, the revised schedule will reduce unnecessary handling of dummy capsules which will reduce personnel exposure. Item 2 concerns the flow verification of the Auxiliary l Feedwater System after an extended outage (>30 days in Mode 5), refueling outages (every 18 months) or modification to the system that could affect the system. It also requires verification of locked valve position and when testing is being performed which requires valve realignment, a dedicated individual will be stationed at the valves with communication to l

the control room who will restore the system to the required line up if l necessary.
